Hello, I've set up a Fedora Core 3 box with squid. Now i want that Squid uses the ntlm_auth for using the Windows 2000 Active Directory Users and Passwords. My smb.conf looks like this: [global] realm = Heumann.local workgroup = Heumann server string = Samba Server printcap name = /etc/printcap load printers = yes cups options = raw log file = /var/log/samba/%m.log max log size = 50 security = ADS password server = 192.168.15.15 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 idmap uid = 16777216-33554431 idmap gid = 16777216-33554431 winbind enum users = yes winbind enum groups = yes template shell = /bin/false winbind use default domain = no The krb5.conf [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = HEUMANN.LOCAL dns_lookup_realm = false dns_lookup_kdc = false [realms] HEUMANN.LOCAL = { kdc = 192.168.15.15:88 admin_server = 192.168.15.15:749 default_domain = HEUMANN.LOCAL } [domain_realm] .heumann.local = HEUMANN.LOCAL heumann.local = HEUMANN.LOCAL [kdc] profile = /var/kerberos/krb5kdc/kdc.conf [appdefaults] pam = { debug = false ticket_lifetime = 36000 renew_lifetime = 36000 forwardable = true krb4_convert = false } And the squid.conf: ... auth_param ntlm program /usr/lib/squid/ntlm_auth auth_param ntlm children 5 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 2 minutes auth_param basic program /usr/lib/squid/ntlm_auth auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours acl AuthorizedUsers proxy_auth REQUIRED http_access allow all AuthorizedUsers .... Now I get the following error in the cache.log >You must specify at least one domain-controller! >(ntlm_auth) usage: >(ntlm_auth) [-b] [-f] [-d] [-l] domain\controller [domain\controller ...] >-b enables load-balancing among controllers >-f enables failover among controllers (DEPRECATED and always active) >-l changes behavior on domain controller failyures to last-ditch. >-d enables debugging statements if DEBUG was defined at build-time. But if i ad in the squid.conf after the ntlm_auth heumann\win2kserv it dosn't work. Wbinfo -u works fine. Please help me.. With best regards Peter213
